Flour / Ag Lime is finely ground oyster shell that has a smooth velvety feel. Its texture and high quality make it highly desirable in numerous commercial and agricultural applications, and well as a feed additive. Available in 50 lb. bags, bulk bags, and in bulk.
- Oyster shell is produced by a living organism Calcium formed in this non-crystalline state is more easily dissolved and utilized by the soil and plants
- Particle shape and texture
Oyster shell calcium is formed in thin, delicate layers that readily break down into flake-shaped particles
The porosity and irregular shape of the shells exposes an immense surface area that reacts with acids in the soil
The oyster shell particles anchor themselves in the soil and resist leaching
- High calcium carbonate analysis
Guaranteed minimum calcium carbonate 96%
Guaranteed minimum calcium 36% (typically 38% – 39%)
Moisture content less than 1% (average .2%)
- Sized specifically to cause a timed release of calcium
1/3 fine particles to produce a rapid pH change (-325 – 200 mesh)
1/3 medium particles to replace calcium as it is leached out or taken up by the plant or turf during the growing season (100 to 60 mesh)
1/3 coarse particles to provide a long-term source of calcium (40 to 20 mesh)
Approximately 55 lbs. per Cu. Ft.
- Oyster shell supplies additional plant growth requirements
